The AG-3150E electronic water sensing system is the only condensate sensor that plugs into the auxiliary drain port of the primary pan & qualifies as an internal primary pan sensor, monitoring condensate directly inside of the primary drain pan. The AG-3150E is a high-amperage, solid-state switch with no moving parts to break down or become clogged. The low profile design makes it easy to install & doesn't interfere with drain lines coming from the HVAC unit.
5 amp high-capacity sensor designed for secondary drains
Eliminates false shut-offs caused by trapped condensation
